Pre-Installation Details
Note: The ice making section cannot be stacked
vertically.
Accessories such as bin adapters and tubing kits are
required to complete the installation.
Dispenser Adapter Kits:
• Cornelius ABS: KBTABS ED150: KBT40
• Scotsman ID150: KBT40
• Scotsman ID200 or ID250: KBT41
Bin Adapter Kits:
• B530P or B530S: KBT32
• B948S: KBT34
Tubing Kits:
• 20 foot: 3BRTE20-EH
• 35 foot: 3BRTE35-EH
• 50 foot: 3BRTE50-EH
• 75 foot: 3BRTE75-EH
Note: Line set may have quick connects. The
condensing section may have quick connects. See
refrigeration system detailed instructions connection
details.
Items required for installation:
• Ice making head
• Condensing unit (includes interconnecting control
system wire)
• Tubing kit. 20’, 35', 50’ or 75’ triple line set (liquid,
vapor and suction)
• Bin or dispenser adapter
Special Considerations
The ice making section’s footprint is 22” wide by 16.5”
deep. The refrigeration connections can be routed up
or to the back. The drain may be routed out the back
at any position left to right; it may also be routed to
either side.
Water
Pure water does not exist. All water supplies contain
some amounts of impurities, although potable water
is, by denition, t for human consumption. Because
the contents of the water to an ice machine directly
impact its performance, consideration should be given
to improving the water’s quality.
There are two ways water can contain impurities:
in suspension or in solution. Suspended solids can
be ltered out of the water. In solution or dissolved
solids must be diluted or treated. Water lters are
recommended to remove the suspended solids.
Some lters or lter systems have treatment
chemicals in them for treating the suspended solids.
This ice machine has an adjustment for the amount
of water rinsed or purged. Water use adjustments
are customer convenience adjustments; they are not
factory defects and are not covered by warranty.

Create the System
Plan the installation. The system consists of three
parts: the ice making head, the condensing unit and
the interconnecting tubing. Of these, the biggest
variable is the interconnecting tubing.
Tubing: The tubing consists of three insulated and
sealed soft copper tubes. One tube, the liquid line,
is 3/8” OD. The vapor tube is ½” OD and the suction
tube is ¾” OD. A site inspection will determine what
length of tubing is required for the installation.
In 2013 Scotsman made a change to the Eclipse
tubing kits:
• Prior Tubing Kits: They each contain a small
holding charge of R-404A and have quick
connects at the ends.
• Current Tubing Kits: The do not contain any
refrigerant and do not have quick connects.
Either type can be used to connect the head and
condensing unit.
Check condensing unit for quick connects. If none,
recover refrigerant from tubing and cut the quick
connects o.
Excess tubing must be shortened at the job site.
Installations with greater than 20 feet of vertical lift
between ice machine and the compressor require
a suction line trap. The suction line requires careful
handling and large radius bends to prevent kinking.
Roof mounting: Some installations will require the use
of a hoist to lift the components to the roof.
Pad mounting: The condensing unit may be located
below the ice making section, up to a limit of 15 feet.
Distance from unit: Limited to the length of the
available tubing.
Elevation: Condensing unit limited to 35 feet above
the ice making section.
Condensing Unit: Electrical power must be supplied to
the condensing unit, it will be separate from the head.
Ice making section location and attachment: The
unique footprint of the MC222 requires adapter kits to
allow placement on dispensers and bins.
The remote tubing connections are at the top of the
machine, and connections should not be made until
the machine is nearly in its nal installed position.
The 115/60 Hz ice making section is cord connected
and requires an outlet within 6 feet of the installation.
Interconnecting wires: An interconnecting wire
harness is included with the condensing unit. One end
plugs into the ice making section and the other into
the condensing unit. The system will NOT operate
without this harness.
Exposed tubing: Minimize the amount of tubing
exposed outdoors.
Lineset Ice machine head and condensing
unit both have stubs
Ice machine head has stubs, condensing
unit has quick connects.
Has Quick Connect Fittings Cut quick connects o both ends Cut o quick connects at condensing unit
end only
Does NOT have Quick
Connect Fittings
Use as supplied Use as is at head, obtain kit KTE6-EH,
use 3 of 6 ttings on condensing unit end.

Place Remote System
Roof preparation
Most installations of this system will place the
condensing unit on the roof of a building. The roof
must be physically able to accept the load of the
equipment and the roong material must be prepared
to prevent water leaks.
Follow local codes for the placement and attachment
of the equipment.
Location
The condensing unit requires unobstructed air ow
to operate eciently. A four foot space between
each intake side and a wall or other cabinet is
recommended.
Do not place where it will pick up hot discharged air
from an air conditioner or other refrigeration system
condensing unit.
Space must also be reserved for service on the
condensing unit.
Roof Piercing:
The roof (or wall) must have a passage large enough
for the three refrigeration tubes and the control wire
to pass through. The minimum recommended size is
4” ID. In most areas the power supply may also pass
through the same passage. If there isn’t a passage
one must be created. In most cases this must be done
by a licensed and bonded roofer in order to maintain
the roof’s integrity.
Roof Pipe Curb or Pitch Pocket:
To avoid potential kinking of the refrigeration tubing,
avoid small, tight radius types of covers on pitch
pockets.
Suggestions:
In most cases a mechanical lift, boom truck or crane
will be required to hoist the condensing unit.
Mount unit to roof rails or curbs and secure with lag
screws or similar eld supplied fasteners.
Orient the assembled unit so that the unit’s mounts
are parallel to the pitch of the roof to allow water to
drain freely.
Do NOT place the unit directly onto roof rock.
In all cases the line set will need to be shortened to t.
Do NOT leave excess line set exposed outdoors,
especially on a roof.
Refrigerant Recovery and System Evacuation Notice
In the event the refrigerant must be recovered from this system and the system evacuated, recover and
evacuate from the three ball valve access valves with the ball valves open.

Lower Light and Switch Panel
This user accessible panel provides important
operational information and duplicates the lights and
switches on the controller. It also allows access to the
On and O buttons that operate the ice machine.
Sometimes access to the switches should be limited
to prevent unauthorized operation. For that purpose a
xed panel is shipped in the hardware package. The
xed panel cannot be opened.
To install the xed panel:
1. Remove the front panel.
2. From the back side of the panel, slide the door

Place Ice Making Head
Remove from carton.
Place adapter kit onto bin or dispenser top. If adapter
does NOT have gasket tape install tape such as
Scotsman part number 19-0503-04. The adapter to
ice head base MUST be sealed with gasket tape or
food grade sealant.
Attachment
ABS (Automatic Beverage Dispenser) in drive up
installations: Route refrigerant tubing and install drain
and water supply tubing onto ice making section
before placing unit on the dispenser.
Place MC222 onto adapter, do not secure at this time.
Uncoil power cord and route to the power supply.
Plug interconnecting control wire to the wire harness
in the ice making head.
Located at the top panel:
• Refrigeration connections.
• Interconnecting control wire.
• Access port for water supply.
• Power cord.
The drain may be routed to the left or right, allowing
the ice making section to be placed with its back tight
against a wall.
Water and Drain
The ice maker requires an adequate potable water
supply and a gravity drain.
Determine how the drain will be connected to the ice
making section.
• If access is available behind the unit, route the
drain in from the back.
• If the unit is to be ush mounted to the back of
the dispenser and tight against the wall, route the
drain out either the left or right.
In some tight situations it will be necessary to
assemble the ice making section to the dispenser or
bin and install the water and drain connections before
placing the system in its installed position. A loop of
water supply tubing will aid movement of the system.
In other tight situations the unit should have its water
and drain tubing connected and stubbed out before
placing on the dispenser or bin.
The drain tting is adaptable to drain connections to
the left, right and back.
The unit is shipped ready to drain right. The drain
tting elbow with PVC adapter can be rotated to drain
right, left or back.

Initial Start Up
Pre Start
A soak-out period of four hours is optional for this
system. If desired, powering the compressor unit
for four hours prior to start up allows the crankcase
heater to warm up the oil in the compressor.
Start Up
1. Connect power to the condensing unit and move
its toggle switch to Run or On.
2. Open the water supply valve.
3. Switch on the electrical power to the MC222.
Observe that some of the lower control’s indicator
lights glow and its display shows O.
4. Locate lower light and control panel.
5. Push and release the ON button on the lower
panel. The code display will begin to blink F.
The purge valve opens, the water pump starts and the
inlet water valve opens to add water to the reservoir.
In a few seconds the purge valve closes and the
water pump stops. Water will ow into the machine
until the reservoir is full. The vapor valve and harvest
assist device will activate, then the compressor and
water pump will start. F will be on steady.
Note: Because the condensing unit is external to the
ice making section, no visible signs of operation will
be noticeable until the water begins to cool and frost
forms on the evaporator tubing.
6. Go to the condensing unit and conrm that the
compressor and fan motor are operating. Warm
air will be discharged from the condenser.
Observe the Ready for Harvest indicator light. It may
blink early in the cycle, that is normal. The control will
ignore that signal for the rst 6 minutes of freeze.
During the Freeze cycle move the curtain and observe
that either the SW1 or SW2 light on the control
board blinks On when the curtain moves away from
the evaporator and O when returned to its normal
position.
Note: Moving the curtain during the Freeze cycle has
no aect on control function, but will cause water to
ow into the cube chute.
When enough ice has frozen, the Ready for Harvest
indicator light will be on steady. After it’s been on
steady for a few seconds Harvest will begin.
The display shows an H. The vapor valve in the
MC222 opens, and the harvest assist mechanism
activates. In the CU the condenser bypass valve
opens and the receiver inlet valve closes. In the
MC222, the purge valve opens to drain some water,
when it does the inlet water valve opens to rell the
reservoir. After a few seconds the purge valve closes
but the inlet water valve continues to ll the reservoir.
Harvest continues until the ice is released as a unit
and forces the curtain to open.
When the curtain opens it signals the controller that
harvest is complete, and it returns the unit to a freeze
cycle.
7. Check the ice harvested for proper bridge
thickness. The ice bridge is factory set at 1/8 inch.
If needed, adjust bridge thickness. Do NOT make
it too thin.
8. Instruct the user in the operation of the machine
and its maintenance requirements.
9. Fill out and mail the warranty registration form or
register it on line at www.scotsman-ice.com.

Adjustable Ice Level Control
There is an adjustment post and an additional
indicator light to the right of the four indicator lights.
The ultrasonic ice level control allows the user to
control the point that the ice machine will stop making
ice before the bin or dispenser is full. Reasons for this
include:
• Seasonal changes in ice used
• Planning to sanitize the bin
• Certain dispenser applications where maximum
ice level is not desired
Use of control
There are several positions the ice level can be set
to, including O (knob and label indicators lined up),
where it lls the bin until the standard bin control shuts
the machine o.
Rotate the adjustment post to the desired ice level.
The machine will ll up to that level and when it shuts
o the indicator light next to the adjustment post will
be On.
Suggested Adjustment Knob Position for use with the
ABS or Freestyle: rst CW position - as shown above.
DO NOT ADJUST TOO LOW OR THE MACHINE
WILL STOP MAKING ICE
Note: Ice will build up in the bin or dispenser at an
angle, the distance set will be from the sensor to the
top of the ice. The sensor position is shown in the
cabinet layout diagrams.
The actual distance between the highest point of the
ice may be closer or further away than the distance
set, depending upon the angle of the ice.
Ice
The cuber drops ice in large sections. That ice will
break up into random parts as it falls into the bin, but
some large sections may remain on top of the ice
in the bin. In a dispenser this ice will break up into
mostly individual cubes as the dispense mechanism
moves the ice.
Noise
The ice machine will make little noise when it is in
ice making mode. The compressor and fan motor are
remote from the ice making head. The water pump
in the ice making head will produce some sound. It
is also normal to hear some cracking just before the
harvest cycle begins. In addition, during the harvest
cycle the harvest assist solenoid will click twice as it
pushes the ice out and returns to its normal position.
The ice harvests as a unit or slab, which makes some
noise when it impacts the bin or dispenser. These
noises are all normal for this machine.

Cleaning, Sanitation and Maintenance
This ice system requires three types of maintenance:
• Remove the build up of mineral scale from the ice machine’s water system and sensors.
• Sanitize the ice machine’s water system and the ice storage bin or dispenser.
• Clean or replace the air lter and clean the air cooled condenser (air cooled models only).
It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without
human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their
water systems with a specically designed chemical. This chemical dissolves mineral build up that forms during
the ice making process.
The ice machine’s water system should be cleaned and sanitized a minimum of twice per year. Sanitize the
ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and
sanitized.
Preparing to Clean:
1. Remove the front panel.
2. Remove the evaporator cover.
Scale Removal:
3. Push and release the Clean button. The yellow
Clean light will blink and the display will show C.
The machine will harvest any ice, drain the reservoir
and begin to rell it.
4. Observe code display, when it blinks the characters
“A d 1” immediately go to the next step.
5. Pour the below specied amount Scotsman Clear
1 ice machine scale remover into the reservoir. The
unit will circulate the scale remover, then drain and
ush it. This will take 35 minutes, then the machine
will stop and the display will show O.
Note: Using chemicals or dilution ratios other than
what is specied will damage the ice machine and
signicantly aect the performance and life of the
ice machine.
Clean internal parts:
6. Mix a cleaning solution of 6oz of Scotsman Clear
1 scale remover with 9 cups (72oz) of 105-115° F
potable water.
7. In a separate bucket, mix a sanitizing solution of 1.6
oz of Nu-Calgon IMS Sanitizer with 1 gallon (128
oz) of 105-115 degree F. potable water.
8. Remove air lter(s)(if applicable), water level sensor
and housing, water distributor(s), curtain(s), ice
thickness sensor, and splash panel for additional
cleaning.
9. Soak and scrub each part (including the
evaporator cover!) using the previously prepared
solution of Scotsman Clear 1 scale remover and a
nylon brush, and then rinse with water. Save scale
remover solution.
10. Soak and scrub each part using the previously
prepared sanitizing solution. No rinse needed. Save
sanitizing solution.
11. Using a non-metallic scouring pad, scrub spillway
with sanitizer to remove any material buildup and
debris.
12. Reinstall ice thickness sensor, curtain(s), splash
panel, water distributor(s), and water level sensor in
their original positions. Be sure water level sensor
and ice thickness sensor are completely dry.

What to do before calling for service
Reasons the machine might shut itself o:
• Lack of water.
• Freeze cycle takes too long.
• Harvest cycle takes too long.
• High discharge temperature.
• Controller self test failure.
Check the following:
1. Has the water supply to the ice machine or
building been shut o? If yes, the ice machine will
automatically restart within 25 minutes after water
begins to ow to it.
2. Has power been shut o to the ice machine? If
yes, the ice machine will automatically restart
when power is restored.
3. Has someone shut the water o to a water
cooled unit? If yes, after the water supply has
been restored the ice machine may need to be
manually reset.
4. Is the curtain open because some ice is stuck
under it? If so, remove the ice and the machine
should start in a few minutes.
To Manually Reset the machine.
• Open the switch door
• Push and release the O button.
• Push and release the On button.
To Shut the Machine O:
1. Push and hold the O button for 3 seconds or until
the machine stops.
Note: Curtain can be removed & replaced anytime the
machine is in a standby mode or when it is in a freeze
cycle. However, removal of the curtain during freeze
will result in water owing into the bin. Removal of the
curtain during harvest terminates harvest at that point
and, if left o, will result in the machine shutting o.
